At the risk of being the new guy that gets everyone mad at him on his first day posting, if you're going to talk about potential without injuries, Bobby Orr replicating his numbers over a 20 year career at defense would be the most valuable player in the history of hockey
I'll build on what @iacas has already said. Last year, you "beat your handicap" if your net score (Score - Handicap) was lower than the Course Rating. With the changes, now you've "beat your handicap" if your net score is Par or better. To me, this is an improvement in the was Course Handicap is calculated, so that "net par" is always a good score.
